Description

Technical Field

[0001] The present application relates to the field of paperboard, in particular to a corrugated paperboard. Background Art

[0002] Corrugated paper is a board-shaped material made by gluing noodle paper and corrugated paper formed by corrugating rollers. It is generally divided into two categories: single corrugated paperboard and double corrugated paperboard. According to the size of the corrugation, it is divided into five types: A, B, C, E, and F. The invention and application of corrugated paper has a history of more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. More than 80% of corrugated paper can be recycled. Corrugated paper can be used as packaging for food or digital products. It is relatively environmentally friendly and widely used.

[0003] During actual use, corrugated cardboard is often subjected to external impacts, causing the objects protected inside to be subjected to external impacts. When the external impact is too large, the corrugated cardboard may be damaged, making it difficult to fully protect the objects away from the impact side. Utility Model Content

[0004] In order to enhance the protection of the corrugated cardboard to objects on one side, the present application provides a corrugated cardboard.

[0005] The present application provides a corrugated paperboard adopting the following technical solution:

[0006] A corrugated paperboard comprises a pressure-resistant layer in the middle, each side of the pressure-resistant layer is fixedly connected to a first pressure layer, the opposite sides of two first pressure layers are connected to a second pressure layer, and the opposite sides of two second pressure layers are connected to an outer layer.

[0007] By adopting the above technical solution and setting the first pressure layer and the second pressure layer, when the corrugated cardboard is subjected to external impact, the objects on one side of the corrugated cardboard can be protected by the alternating support of the first pressure layer and the second pressure layer, thereby reducing the phenomenon that the corrugated cardboard is damaged when subjected to external impact and the objects on one side of the corrugated cardboard are harmed.

[0008] Optionally, the cross-section of the first pressure layer is configured to be composed of a plurality of hexagonal paperboards.

[0009] By adopting the above technical scheme, the first pressure layer composed of multiple hexagonal cardboards can fully bear the external force. When impacted by external force, the end of the hexagonal cardboard is subjected to force. On the one hand, the first pressure layer can fully resist the external force to reduce the damage of the corrugated cardboard. On the other hand, since the end of the hexagonal support plate is in contact with the external impact, the deformation of the corrugated cardboard when subjected to external impact is also reduced.

[0010] Optionally, the vertical cross section of the second pressure layer is configured to be composed of a plurality of V-shaped paperboards.

[0011] By adopting the above technical solution, by setting the second pressure layer to be composed of multiple V-shaped support plates, when subjected to external impact, part of the impact can be absorbed by the deformation of the second pressure layer, thereby reducing the impact transmitted to the first pressure layer, and reducing the phenomenon of corrugated cardboard being damaged during the impact.

[0012] Optionally, a reinforcement layer is provided between adjacent first pressure layers and second pressure layers.

[0013] By adopting the above technical solution and setting a reinforcement layer, it is possible to reduce the possibility that when the second pressure layer is deformed by external impact, the deformed part is inserted into the middle position of the hexagonal paperboard of the first pressure layer, thereby making it difficult for the first pressure layer to directly withstand the external impact and cause the first pressure layer to fail. In addition, by setting a reinforcement layer, the local impact received by the first pressure layer can also be dispersed, so that the first pressure layer can withstand external impacts of greater intensity.

[0014] Optionally, a fireproof layer is connected between the opposite sides of two second pressure layers and the adjacent outer layers.

[0015] By adopting the above technical solution and providing a fireproof layer, the risk of the corrugated cardboard itself becoming a fire source and causing damage to the object protected on one side, or the damage to the surrounding environment caused by the burning of the corrugated cardboard itself, is reduced when the corrugated cardboard is placed in a high temperature environment or a fire occurs outside, due to the material of the corrugated cardboard itself.

[0016] Optionally, a camphor layer is connected between each of the second pressure layers and the adjacent outer layer.

[0017] By adopting the above technical solution and providing a camphor layer, the corrugated cardboard can be kept away from insects and rats during long-term storage, thereby reducing the risk of the corrugated cardboard being pierced by insects and rats, and further reducing the risk of damage to one side of the object due to insects and rats gnawing on it.

[0018] Optionally, a waterproof layer is connected between each camphor layer and the adjacent outer layer.

[0019] By adopting the above technical solution and providing a waterproof layer, the possibility of the corrugated cardboard being damaged by water vapor when the corrugated cardboard is placed in a humid environment after wrapping an object is reduced, making it difficult to protect the object wrapped inside, resulting in the internal object being damaged by water vapor. At the same time, the possibility of the camphor layer being unable to play a normal role in contacting water vapor to repel insects and rats is also reduced.

[0020] Optionally, the opposite sides of the two outer layers are fixedly connected with an anti-fouling layer.

[0021] By adopting the above technical solution and providing an anti-fouling layer, the phenomenon of the corrugated cardboard being polluted externally during use, which affects the normal use of personnel and causes the corrugated cardboard to be discarded, is reduced.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By providing the first pressure layer, the second pressure layer and the reinforcement layer, the bearing capacity of the corrugated paperboard when subjected to external impact can be improved, and thus the protection capacity of the corrugated paperboard to objects on one side when subjected to external impact can also be improved;

[0024] 2. By setting up a fireproof layer and a waterproof layer, the protection ability of the corrugated cardboard to objects on one side can be improved when it is in a high temperature or humid environment;

[0025] 3. By providing a camphor layer, when the corrugated cardboard is in a space where insects and rodents exist, the camphor layer can drive away the surrounding insects and rodents, thereby protecting the corrugated cardboard and objects on one side of the corrugated cardboard;

[0026] 4. By setting up an anti-fouling layer, the outer layer of the corrugated cardboard can be protected, allowing personnel to more easily clean the stains on the outer layer, so that the corrugated cardboard can maintain a good appearance, reducing the phenomenon of personnel discarding corrugated cardboard due to a large number of stains on the surface of the corrugated cardboard, thereby indirectly increasing the service life of the corrugated cardboard.
